使用C ++ 11线程的简单代码:
#include <iostream>
#include <thread>
#include <string>
using namespace std;
void thread_task(){
std::cout<<"hello, here is thread task with state:"<<std::endl;
}
int main(int argc, char *argv[])
{
std::thread t(thread_task);
t.join();
return 0;
}
编译:
g++ -pthread -std=c++11 -O0 -Wall -g -ggdb main.cpp -o main -lboost_system -lboost_filesystem -lboost_serialization
./main can execute right!
-
g++ -pthread -std=c++11 -O0 -Wall -g -ggdb main.cpp -o main -lboost_system -lboost_filesystem -lboost_serialization -lboost_container-mt
g++ -pthread -std=c++11 -O0 -Wall -g -ggdb main.cpp -o main -lboost_system -lboost_filesystem -lboost_serialization -lboost_container
./main all will have an error:
terminate called after throwing an instance of 'std::system_error'
what(): Enable multithreading to use std::thread: Operation not permitted
[1] 29643 abort (core dumped) ./main
为什么-lboost_container会导致此错误?当然,我的代码示例中不需要boost_container。这只是一个例子。
